Objective:To explore the mediating role of self-perceived aging in the relationship between perceived social support and self-efficacy for exercise in aged patients undergoing surgery for lung cancer and provide a basis for formulating relevant clinical intervention strategies.Methods:Totally 220 aged lung cancer patients who underwent surgery and were hospitalized at the Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, from April to June 2024 were recruited by convenience sampling. Patients completed a demographic questionnaire, the Self-Efficacy for Exercise (SEE) , the Ageing Perceptions Questionnaire (B-APQ) , and the Perceived Social Support Scale (PSSS) . The mediation effect of self-perceived aging between perceived social support and self-efficacy for exercise was analyzed using Model 4 in the SPSS Process macro.Results:A total of 220 questionnaires were distributed, and 207 valid questionnaires were returned, with an effective recovery rate of 94.09%. The total score for B-APQ was (46.93±11.35) , the SEE score was (44.12±12.83) , and the PSSS score was (53.18±13.53) . Perceived social support had a direct effect on self-efficacy for exercise (effect value: 0.278; P<0.01) . Self-perceived aging played a partial mediating role between perceived social support and self-efficacy for exercise, with a mediation effect value of 0.138 ( P<0.01) , accounting for 33.17% of the total effect (0.138/0.416) . Conclusions:Perceived social support directly influences self-efficacy for exercise in aged patients undergoing surgery for lung cancer and also exerts an indirect effect through self-perceived aging. It is recommended that healthcare providers guide these patients to establish a positive perception of aging while focusing on enhancing their social support levels to improve their self-efficacy for exercise and promote recovery.

ObjectiveTo construct and validate a clinical prediction model for Qi deficiency and blood stasis syndrome in chronic heart failure （CHF），aiming to assist clinical diagnosis and provide tools and methods for individualized treatment of CHF. MethodsThe clinical data of patients with chronic heart failure treated at Dongzhimen Hospital of Beijing University of Chinese Medicine from January 2022 to January 2024 were retrospectively collected. The patients were randomly divided into a training group and a validation group with a ratio of 7∶3. First， the least absolute shrinkage and selection operator （LASSO） regression analysis was used to preliminarily screen the predictive factors affecting the diagnosis of Qi deficiency and blood stasis syndrome in CHF. Subsequently， the Logistic regression method was applied to conduct a more in-depth and detailed analysis of these factors. Variables with P<0.05 in the results of the multi-factor Logistic regression were carefully selected and included. Based on the regression coefficients obtained from this analysis， a model was constructed， and a nomogram was accurately drawn. Using R software，the receiver operating characteristic （ROC） curve，calibration curve，and decision curve analysis （DCA） were precisely drawn. These analyses were used to comprehensively evaluate the model from three crucial aspects： discrimination，calibration，and clinical applicability. Additionally， the accuracy，specificity，sensitivity，positive predictive value，and negative predictive value of the model were meticulously calculated to conduct a more all-round and comprehensive assessment. ResultsIn total， 168 cases were successfully obtained in the training group， and 71 cases were included in the validation group. After a thorough comparison， it was found that there were no statistically significant differences in the baseline data between the two groups. After being rigorously screened by the LASSO-multivariate logistic regression method， dark red tongue，smoking history，cardiac troponin I，and N-terminal pro-B-type natriuretic peptide （NT-ProBNP） were identified as the influencing factors for diagnosing patients with the Qi deficiency and blood stasis syndrome in CHF. The constructed model demonstrated an area under the curve （AUC） of 0.812 in the training group and 0.719 in the validation group. The calibration curve showed that the predicted curve of the model was close to the actual observed curve. DCA indicated that the model could provide substantial clinical benefits for patients at the decision thresholds ranging from 0.2 to 0.9. ConclusionThe clinical prediction model for Qi deficiency and blood stasis syndrome in chronic heart failure constructed in this study shows good performance. It has certain application value in clinical practice， which may contribute to the improvement of the diagnosis and treatment of CHF patients with this syndrome.

Objective:To study the diagnostic value of the artificial intelligence (AI) diagnostic system, ACR TI-RADS classification and AI+ ACR TI-RADS combined diagnostic performance in benign and malignant thyroid nodules and its guiding significance for surgical treatment.Methods:From Nov. 1, 2021, to Feb. 26, 2022, 349 patients with 605 thyroid nodules who received surgical treatment in Department of Thyroid (Hernia) Surgery, Department of General Surgery, the First Medical Center of the PLA General Hospital, were selected. There were 95 males and 254 females, male: female=1:2.67, aged 16-78 years, and the nodule diameter was 0.2-5.6 cm. SPSS 26.0 and R studio software were used for data processing. AI diagnostic system, ACR TI-RADS grading and AI+ ACR TI-RADS combined diagnostic efficacy were statistically analyzed, respectively. ROC curve analysis was performed in parallel.Results:The AUC value of AI+ ACR TI-RADS combined diagnosis was 0.900, greater than 0.857 of AI diagnostic system and 0.788 of ACR TI-RADS, and the difference was statistically significant ( Z= 7.631, both P<0.001) . The sensitivity of the combined diagnosis was 95.32%, the specificity was 84.61%, the accuracy was 92.56%, the positive predictive value was 94.69%, the negative predictive value was 86.27%, the missed diagnosis rate was 4.68%, and the misdiagnosis rate was 15.38%, which were better than the other two diagnostic methods. With an excellent coincidence rate with postoperative pathological results ( Kappa=0.804, P<0.001) . The accuracy of combined diagnosis in identifying the maximum diameter of different tumors was 89.58% for d≤0.5 cm, 96.09% for 0.54.0 cm, better than the other two diagnostic methods. Conclusions:The combined application of AI+ACR TI-RADS has a certain primary screening value in evaluating thyroid nodule properties. The combined diagnosis of the two can more effectively determine the benign and malignant thyroid nodules.

OBJECTIVE To study the quality difference of different specifications of Citri Grandis Exocarpium from different origins，and to provide reference for the orderly development of Citri Grandis Exocarpium industry. METHODS Different specifications [ Citrus grandis ‘Tomentos’young fruit ，Citrus grandis （L.）Osbeck young fruits ，exocarp] of 93 batches of Citri Grandis Exocarpium medicinal materials （decoction pieces ）from different origins [ Citrus grandis ‘Tomentosa’or Citrus grandis （L.）Osbeck] were taken as samples. The contents of naringin and rhoifolin in samples were determined by HPLC. Through pheatmap parameters of R language ，heatmap was drawn for the contents of naringin and rhoifolin according to origins and specifications （young fruit and exocarp ）. RESULTS Of 93 batches of samples ，the contents of naringin and rhoifolin were 16.52-214.64 and 1.03-10.96 mg/g，respectively. Among different specifications ，the contents of naringin and rhoifolin in the young fruit were the highest （their average contents were 108.96 and 6.30 mg/g respectively ）. Heatmap analysis of R language content showed that the contents of naringin and rhoifolin in Citri Grandis Exocarpium from origin of C. grandis ‘Tomentosa’were generally higher than those from origin of C. grandis （L.）Osbeck. Of different specifications of Citri Grandis Exocarpium from origins，the contents of naringin and rhoifolin were higher in KTP young fruit relatively. CONCLUSIONS The quality of Citri Grandis Exocarpium from origin of C. grandis ‘Tomentosa’with the young fruit as specification is the best.
